' CUSHION TIRE ANDMETHOD OFYAPPLYING sai/mf i l My present invention relates Vto' improve-` Y ments in cushion tires-and method ot' apply- 1 ing same, having a rubber cushion body containing 'an internal circumferentially eX- 5 ytending cavityland vulcanized onto ak plu-` rality of parallel metalrings which form the tire base which is adapted to be secured to the rim or felloe of-a vehicle wheel by being forcibly pressed thereonwith its invlo ternal periphery tightly squeezing theouter b f `rings 8 and 9 by means of the hard vrubber periphery of the wheel rim or elloe.

v My principal object is to so construct v and arrange the parallel metal ringslform'- ing the tire base, that they will be adapted 4to retain during the pressing on operation, f that the cavlty'lt in'thetire body vislocated pieces ofshimming :material .placed on the innerperipheryjof one ormoreof the rings? to enable such ringsto squeeze a portion of vthe wheel rimthat is of 'smallerdiameter` as tightly' asone or Vmore oftheother rings Y squeeze'an'other larger diameter.
